Hydrogen-ready steel: how Salzgitter’s SALCOS hot strip shapes greener coils

Low-carbon flat steel is moving from pilot projects to day-to-day procurement, and Salzgitter’s SALCOS hot strip is one of the first large-volume products in Europe positioned as an industrially scalable, hydrogen-based alternative to conventional coil.

The product is rolled at Salzgitter’s integrated site but increasingly based on direct-reduced iron and electric arc furnaces rather than classic blast furnaces, with the company targeting up to 95 percent lower CO2 intensity for SALCOS-based steel compared with its historical baseline. The manufacturer’s SALCOS overview sets out a multi-stage transformation of the plant, from the first direct reduction module and new EAFs to a full phase-out of traditional ironmaking.

What SALCOS hot strip is designed to deliver

In technical terms, SALCOS hot strip is a family of hot-rolled flat steel grades that can be produced with a significantly reduced carbon footprint using green hydrogen in direct reduction modules, then melted in electric arc furnaces and processed on existing rolling mills.

While the exact emissions footprint depends on the transformation stage and energy mix, Salzgitter markets SALCOS steel against externally audited CO2 data and offers product-specific emissions declarations to automotive, machinery and energy customers that are starting to account for embedded carbon in their supply chains.

For buyers, the key point is that SALCOS hot strip is not a separate experimental product line but is intended to cover common flat steel grades used in automotive body parts, engineering, tubes and sections, meaning it can often be specified as a lower-CO2 variant within existing material families.

The company couples this with digital documentation to track the production route and carbon footprint of each batch, a feature that is increasingly requested as regulations such as the EU’s Carbon Border Adjustment Mechanism and evolving corporate reporting rules put pressure on Scope 3 emissions.

By combining a new ironmaking route with established hot strip mills, Salzgitter aims to give customers a drop-in alternative that limits qualification effort while still offering measurable CO2 reductions compared with blast furnace-based coils.

Hydrogen supply and pellet technology as enablers

A pivotal question for any hydrogen-based flat steel is security of supply, and Salzgitter has put a marker down through a long-term agreement under which EWE plans to deliver around 10,000 tonnes of green hydrogen per year to Salzgitter Flachstahl from 2030, providing a key input for the SALCOS direct reduction plants. An industry report on the deal highlights the seven-year term and describes it as the first major hydrogen supply contract for green steel production in Germany.

On the raw-material side, the company is also involved in testing a new green pellet technology together with specialist firm Binding Solutions, with the aim of producing high-quality iron ore pellets suitable for direct reduction while lowering the environmental impact of agglomeration.

If these technologies scale as planned, they would not only underpin the SALCOS hot strip product with low-carbon upstream inputs but also improve resilience in a market where high-grade iron ore and DR-grade pellets are becoming strategic resources.

The combination of secured hydrogen volumes and progress on pelletization is central to Salzgitter’s message that decarbonized hot strip will be available in industrial quantities, not just for niche demonstrator projects.

For customers, this matters because supplier roadmaps increasingly factor into long-term contracts and investment decisions, particularly in sectors like automotive where model cycles run over many years and material strategies are locked in early.

Market positioning in Europe’s green steel race

Among European flat steel producers, Salzgitter is positioning its SALCOS hot strip as a core product in the emerging green steel segment, targeting sectors that are willing to pay a premium for certified CO2 reductions and secure long-term volumes.

At the same time, the company faces competition from other producers in Sweden, Germany and further afield that are building similar hydrogen-based or direct reduction projects, meaning that technical performance, price structure and quality consistency of hot strip coils will determine how much market share SALCOS-based products can capture.

Salzgitter’s integrated site offers the advantage of having coking plants, sinter, blast furnaces, converters and rolling mills already in place, enabling a staged transition where SALCOS hot strip can ramp up as new modules come on stream while conventional products continue to serve customers who are not yet prepared to switch.

By signaling large-scale investment and providing concrete product offerings today, the company aims to lock in long-term relationships with carmakers, white-goods manufacturers and energy equipment suppliers that are under pressure to decarbonize their own products.

How quickly SALCOS hot strip volumes can grow will depend on project execution, permitting, power prices and the development of a robust hydrogen infrastructure in northern Germany.

Financial and strategic relevance for the group

SALCOS hot strip sits at the center of Salzgitter’s broader SALCOS transformation program, which is one of the group’s largest investment projects and is expected to gradually reshape its flat steel earnings profile over the coming decade.

The company highlights decarbonized steel products as a pillar of its “Salzgitter AG 2030” strategy and has signaled that climate-friendly flat steel could open up new long-term contracts and potentially more stable margins in segments where buyers are willing to pay for certified CO2 reductions.

At the same time, the capital intensity and execution risk of building direct reduction modules, electric arc furnaces and the associated hydrogen and power infrastructure mean that delivering competitive hot strip products will be critical to earning an adequate return on these investments.

For now, SALCOS hot strip functions as both a commercial product and a proof point to customers and investors that the group’s decarbonization roadmap is translating into tangible offerings with defined technical parameters.

Salzgitter is publicly listed in Germany, and its transformation narrative, including the rollout of SALCOS-based products such as low-CO2 hot strip, is a recurring topic in investor communications and external analysis. A recent valuation review discusses how the company’s long-term hydrogen and green steel commitments factor into market expectations for the stock.

Shares of Salzgitter AG (DE0006202005) are traded on the Xetra segment of the Frankfurt Stock Exchange in euros, giving investors direct exposure to the group’s progress in decarbonized flat steel alongside its traditional steel and technology businesses.
